The HD25.2 instrument can be connected to a personal computer via an RS232C serial port or USB
port, and exchange data and information through the DeltaLog11 software running in a Windows
operating environment. It is possible to print the measured value on a 24 column printer (PRINT
key) and store it in the internal memory using the logging function (MEM key). The stored data can
be recalled to be viewed directly on the instrument display and then printed or transferred to the PC
(menu command “
CONFIRM DUMP ALL MEA? ”).

UNCTION
The instrument allows the recording of up to 999 samples in its internal memory. After having
performed a measurement (MEAS key), press
MEM : a counter displays for a few seconds the data
memory location: “m###”. If the measurement was already recorded, the “ ALREADY MEM ”
error message appears.
The data stored in the memory can be transferred to a PC using the DeltaLog11 software: please see
the software help for the details.
To display the recorded data directly on the instrument display, use the “
DISPLAY LOG ” menu
command (please see the details on page 8).
To print the current screen, press the
PRINT key.

LEARING THE

EMORY
To clear the memory, open the menu and select the item “ CONFIRM ERAS ALL MEA? ”. Use
the arrow to select “YES” and confirm with ENTER.
The instrument starts clearing the internal memory; at the end of the operation, it goes back to
normal display.
Warning: the cleared data cannot be recovered.
NOTES:
•
The data transfer carried out using the DeltaLog11 software does not cause the memory to be
erased; the operation can be repeated as many times as required.
•
The recorded data remain in the memory even if the instrument is turned off, disconnected from
the mains or if the batteries are removed.
•
In order to print the data to a parallel interface printer, you must use a parallel-serial adaptor (not
supplied).

FUNCTION
Press PRINT to send the displayed page directly to the RS232 or USB port.
A printer with serial input can be connected to the RS232C port (e.g. the Delta Ohm 24 column
printer code
S’print-BT ). The RS232C and USB ports can be connected to the corresponding ports
on the PC using the appropriate cables: 9CPRS232 for the RS232C serial, CP22 for the USB.
The instrument detects automatically the presence of a connection to the USB port: in this case the
RS232C serial port is disabled.
